Mordru is an odd case in that he seems to always scale to whatever version of Fate he is fighting. No explanation is ever really given for this as far as I am aware, but he most consistently faces off against Kent, and he never faces Linda and Eric. You could argue that this scales all versions of Fate to each other, but it's really the only feat that does that so I'm uncertain of its legitimacy. I guess this is
kind of taken care of in Nabu's final battle with him, during which the two are pretty evenly matched despite Nabu waning in power, but it still doesn't mesh with Mordru being considered one of the most powerful Lords of Chaos, which scale to Nabu.
Time Trapper scales to Mordru, The Infinite Man scales to Time Trapper, and Parallax also scales to Time Trapper.
Darkseid can scale to Kent, but we cannot scale him to the Lords of Order and Chaos because of how weird that meeting was in my opinion. First of all, it ocurred during the Eric/Linda era, when Fate characters were being downplayed a lot. Even Nabu was only
described as a universal consciousness during that ru. Secondly, Chaos claims they don't actually fear Darkseid but
instead respect him as an agent of theirs.
It's unclear which one is correct. And thirdly, the entire event was retconned as not being Darkseid but instead
Desaad disguised as Darkseid. It's clear nobody was really happy with how the interpretation turned out.
Trigon should scale to both the Spectre (
being in the same tier of power) and Dr. Fate directly (
likely being above his strongest incarnatio).
The Spectre (Jim Corrigan) can scale to a 2-A Fate, but he cannot scale to a High 2-A version. Fate has High 2-A feats later in his run (one even involving a High 2-A Spectre), but these feats do not start ocurring until years after Crisis on Infinite Earths. What you want to do with that information is your own perrogative.
The Spectre (Hal Jordan) should scale above Parallax.
Pre-Crisis Superman also scales to Kent, but I don't know how much that matters because Kent is still probably beyond him at the end of the day. He's been shown doing things like staggering Fate with his punches, surviving Darkseid, threatening Fate with the help of Martain Manhunter, threatening Darkseid with the help of Supergirl, taking hits from Time Trapper, etc. Being comperable isn't being equivalent, so I don't know if it warrants an upgrade, but it's only relevant if Kent Fate specifically gets a 2-B tier.
The Phantom Stranger scales equivalent to or above the most powerful version of Doctor Fate. The version used on this site specifically scales to a form of magic explicitly stated to be above Doctor Fate.
